Turns out things get a bit tricky when mdirs are dropped while iterating
over the mtree.
This was actually broken quite a bit before traversal-related changes,
probably during some mtree refactor, but went unnoticed since no test
actually checked that lfsr_fs_fixorphans did what it said it did.
At least the new test_forphans_cleanup* tests should prevent this from
regressing again in the future.
